Specimens were prepared and loaded into three in-core canisters of the Materials Open Test Assembly (MOTA) for irradiation during FFTF cycle 4 (January-April 1984). Irradiations were conducted at 407/sup 0/C (6-11 dpa), 518/sup 0/C (14-16 dpa) and 595/sup 0/C (14-16 dpa). Alloys emphasized in this initial irradiation were the Path E ferritic alloys HT-9 and 9 Cr-1Mo, and the Path C vanadium alloys. These specimens were either discharged or reinserted into new MOTA hardware for irradiation during FFTF cycles 5-6 (June 1984-June 1985). New specimens were also included, and additional irradiation volume both in-core and below-core was available for an expanded test matrix. Irradiations are currently underway during cycles 5-6 at 365/sup 0/C (below-core: 4-7 dpa), at 425, 520 and 600/sup 0/C (all 25-28 dpa) and 600/sup 0/C (8-14 dpa). Additional emphasis on low activation alloys was given for this irradiation. Specimens in the peak flux positions during cycles 4-6 will accumulate approximately 45 dpa.
